Was verursacht dieses Problem?

The control limits for track &V1& on the control chart cannot be
calculated with the existing data.

Systemantwort

The function was not carried out.

Wie behebe ich diesen Fehler?

The procedure depends on the type of track and the type of inspection
characteristic. The following options are available:
In the case of an average value track, the standard deviations of the
samples are required to calculate the limits.
In the case of <ZH>summarized recording</>, you can enter these in the
single screen for the characteristic.
In the case of <ZH>classified recording</> or <ZH>recording of
individual values</>, the standard deviation is only determined
automatically during the valuation. In order to initiate the
calculation before the valuation is performed, call the function for
recording the statistical moments.
In the case of an average value track for an acceptance chart, if the
dispersion is large or the tolerance range is small, then the value
for the upper control limit can sometimes be less than that of the
lower control limit.
If this happens, then you should repeat the calculation at a later
date,when the dispersion has decreased.
Individual algorithms can often require a certain minimum number of
inspection results before a calculation is possible.
The exact requirements depend on the procedure stored for the track in
the Customizing application.
